TRUCK DESIGN OPTIMIZATION PROJECT FIELD TEST DATA, SERIES 5, TAPE TDOP 0117

The 3 data files on this magnetic tape include acceleration, force, and displacement measurements at critical points on a freight car and truck. Each file includes detailed alphanumeric descriptions of test conditions. The following are for all tests on this tape: Car-70 Ton M. Reefer* Truck-ASF Ride Control* Truck Center-45 Ft. 9 In.* Load-Full* Wheel Profile-Cylindrical* Spring Group 7-D3O; 2-D3I* Snubbing-8-3091* Snubber Augmentation-None* Centerplate Friction-Steel-Moly* Additional Experimental Devices or Conditions-None* NOTE: Vertical adapter forces are subject to question. Those on sharper curves or empty cars at high speed are least accurate. Individual variations of the different tests are as follows: FILE 1: Name-050204MOD001* Track-Shimmed* Speed-12 to 20 in 2 mph steps* Outer Gib Clearance-5/8 In.* Side Bearings-1/4 In. Clear.* Additional Experimental Conditions-None* Errors noted-ch. 23 +0.3; ch 47 -0.3 volts off 0; ch. 14 and 40 interchanged ***FILE 2: Name-050204TSM001* Track-Med.Spd.Jtd.* Speed-15 to 45 in 5 mph steps* Outer Gib Clearance-5/8 In.* Side Bearings-1/4 In. Clear.* Additional Experimental Conditions-None* Errors noted-ch. 14 and 40 interchanged ***FILE 3: Name-050204TWA001* Track-Hi.Spd.Jtd.* Speed-30 to 79 in 10 mph steps* Outer Gib Clearance-5/8 In.* Side Bearings-1/4 In. Clear.* Additional Experimental Conditions-None* Errors noted-ch. 14 and 40 interchanged; ch. 32 +0.5v. off 0.
